Hi,

I'm currently struggling with the semantics of the transmissibilities, and 
given the number of Eclipse gurus on this mailing list, I thought somebody may 
know the answer: To compute the TRANSX value for a cell i, the Eclipse TD says 
that one needs to harmonically average T_i and T_j, the "half-face" x-
transmissibilities of the "interior" cell  and the "exterior" cell of a face. 
Here the problem arises: Transmissibility is a quantity which inherently only 
makes sense for cell faces in finite-volume discretizations but Eclipse 
specifies it as a cell-based quantity. Considering that because of faults the 
grid can become non-conforming and there can thus be more than one face into 
each direction, the TRANS[XYZ] keywords do not really make sense. The question 
is: What must be assumed as the "cell j"? The cell which is one index further 
in logically Cartesian coordinates? (That would not work for faults or for 
cases where those cells are not connected, though.)

cheers
  Andreas
